Always refer to this information before starting trial operation in the following instances:
D 4.2.1 Servomotor with Brakes
D 4.2.2 Position Control by Host Controller
Use Servomotors with brakes for vertical shaft applications or when external force is applied to
the shaft to prevent the shaft from rotating due to gravity or external force when power is lost.
The Servopack uses the brake interlock output (/BK) signal to control holding brake operation
when using Servomotors with brakes.
D Vertical Shaft
Servomotor
Holding brake
Prevents the
Servomotor from
rotating due to gravity.
To prevent faulty operation due to gravity or external force, make sure that the Servomotor and holding brake
operate normally with the Servomotor disconnected from the equipment. When both of them operate normally,
connect the servomotor to the equipment to start trial operation.
The following figure shows wiring for a Servomotor with brakes. See 5.4.4 Using the Holding
Brake for details on wiring.
